Discovery of the Ununpentium Element
The element was
discovered in 2003 by scientists working at the Joint Institute
for Nuclear Research in Dubna, Russia together with scientists
from the U.S. Department of Energy's Lawrence Livermore National
Laboratory. The scientists produced Ununpentium using atoms of
americium-243 which were bombarded with ions of calcium-48 using
a device called a cyclotron which is a research instrument with
which several new elements have been first produced. This produced one atom of ununpentium.
Element 115, Ununpentium - will probably be a basic metal. Nearly 75%
of all the elements in the Periodic Table are classified as
metals which are detailed in the
List of Metals.
Ununpentium currently has no uses outside of basic scientific

Ununpentium - IUPAC and the
Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the
International Union of Pure Applied Chemistry, IUPAC, in 1985 and
now recognises more periods and elements than
Mendeleev knew in his day in his day but still all fitting into his concept of
the "Periodic Table" in which
Ununpentium is just one element
that can be found.
